TIE. ron ANCHORING FLOOR SLEEPERS.

Application filed May 8, 1923. Serial No. 637,551.

To all whom it may concern: i

Be it known that I, JOHN A. WVHITTAKER, citizen of the United States, residing Detroit, county of lVayne, State of Michigan, have invented a certain new and useful Improvement in Ties for Anchoring Floor Sleepers, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilledin the art to which it pertains to make and use the same, reference being had to the accom-.

plastic condition, the strips being inserted so they will project above the plane of the slab for attachment to thefloor sleepers.

This device has been found objectionable because of the difficulty of inserting and lining up the strips in the concrete bed, and furthermore it requires the workman to walk over the plastic surface of the concrete bed, first to insert the strips in the" concrete bed and then to nail them to the sleepers laid upon the slab; and as the surface of the .concrete slab may be more or less uneven it is difficult to properly a-line the strips so that their upper edges will be on an even plane.

To overcome these and other objections I have provided a device constructed of sheet metal bent to a yoke shaped form, the construction being such that it is adapted to be inserted in transverse ke-rfs cut in the floor sleeper, the downwardly projecting ends of the device being bent to provide footings on a plane with the lower edge of the floor sleeper when mounted therein. 7

A concrete filling is then poured between the floor sleepers thereby embeddingin the concrete filling the downwardly projecting members of the ties, the concrete filling when complete being substantially on a plane with the top of the sleeper.

In the drawings accompanying this specification:

Figure 1 is a perspective view of the de Figure 2 is a vertical fragmentary crosssectional view through a floor sleeper, concrete slab and filling, showing the ties in position. I

Figure 3 is a fragmentary plan view of a concrete floor base with floor sleepers in position and the ties in place as they would appear prior to being covered by the concrete filling.

Referring now to the letters of reference placed upon drawings:

A denotes a concrete bed or slab as usually provided to receive wooden floor sleepers B laid tthereon in spaced relation to each other. v

C designates a sleeper tie, constructed of sheet metal its central vertically disposed portion (3 being adapted to enter a trans verse kerf cut in the top of the floor sleeper. The tie is bent as clearly shown in Figure 1 so as to provide downwardly extending por' tions C, C", parallel with the sides of the wood sleeper! and terminating in footings 0, 0, projecting outwardly on a plane with the lower edgeof the sleeper.

D indicatesv a. concrete filling poured between the sleeper and overlapping the tie footings as clearly indicated in Figure 2; the wooden floor sleepers are thus held against displacement. v

E denotes a wooden flooring secured by nails F to the sleeper B. r

When inserting the ties in the floor sleepers it is not necessary for the workman to cut a kerf in the sleepers of a depth equal to the'width of the tie, all that is required is a cut sufficiently deep that the edge of the tie may be inserted and then driven by a blow of the hammer sothat its upper edge will be flush with the top of the floor sleeper. After coverin the footings of the respective ties and filling the spaces between the sleepers with concrete the flooring may be nailed to the sleepers.

It will be seen that in the use of this device it is not necessary for the workman to walk over the concrete slab while in a. plastic condition to insert strips or to nail them to the wood sleepers.

Having thus described my invention what I claim is:

1. A device for anchoring floor sleepers to a concrete slab comprising astrip of metal :bent to provide a horizontal intermediate portion having its sides arranged in a vertical plane and at the ends of said horizontal portion twisted and directed downwardly to provide spaced parallel legs having their sides at a right angle to the plane of the sides'of the intermediate horizontal portion and which terminate at their lower ends in feet portions directed outwardly.

2. In combination with a floor sleeper adapted for installation upon a concrete slab and provided with a plurality of transverse slots, a strip of metal adapted for insertion inthe transverse slots of the sleeper, bent to provide a horizontal portion having its sides arranged in a vertical plane in the respective slot and at the ends of the horizonsleeper and parallel therewith and spaced 7 therefrom, the lower ends of said legs being bent outwardly to form horizontally disposed foot pieces, adapted to rest upon the concrete slab, and a filling of concrete overlapping said foot pleces to a plane substantially level with the top of the floor sleepers and contiguous to the side walls of the latter. In testimony whereof, I sign this specification in the presence of two witnesses.
